IPC: H04M3/42
Filed: 1994-06-27
Abstract: A method of mediating mes-sage traffic across interfaces open to third parties in an Advanced Intel-ligent Network for a switched tele-phone system is disclosed. Network utilization is monitored by maintain-ing message counts at the open inter-faces and rejecting messages or termi-nating access via the interface when an excessive rate of traffic is detected. Access to data bases stored in ser-vice control points is used to deter-mine if the sender indentified in the contents of the message is the same as the entity authorized to use the physi-cal port upon which the message was received. Also, customer records in the service control point are tested to determine if the sender of the records in sage is authorized to affect the call progress of an affected customer di-rectory number identified in the mes-sage. Upon termination of the mes-sage traffic across a port, a defaut application is activated so that other network elements do not have to rely on timeouts to continue processing of calls.

Inventor: BLOW KEITH JAMES
IPC: H04B10/70
Filed: 1994-09-08
Abstract: In a method of communication using quantum cryptog-raphy an encryption alphabet is used for coding signals for on a quantum channel. The encryption alphabet comprises pairs of operators applied successively to single-photon signals transmitted onto the quantum channel with a pre-determined delay between them. When the signals are detected, the different signals of each pair are split according to their encoded state and directed to different detectors via paths giving a differential delay. The delay is substantially complementary to the original pre-determined delay. Coin-cidence detection is employed at the detectors to eliminate spurious detection counts.

Abstract: A bomb damage assessment system (10) that is carried by a weapon (11) and released to provide imagery of a bombed area before and after bomb delivery. The system (10) comprises a glider. (20) that is releasably secured to the weapon (11) that includes tracking and guidance electronics (34, 40) for programmable controlling the flight thereof. An imaging system (31 ) is disposed in the front end of the glider (20) and a deployable ballute (27) is disposed at the rear end thereof. A data link (36) is provided for transmitting images to a command center for review. The system (10) provides imagery of a target area before, during and after weapon impact.  Television or infrared cameras (31) may be used for day or night missions. As a target area is approached, the glider (20) is released, resulting in an aerodynamic vehicle that flies much slower than the weapon (11). The imaging system (31) tracks the weapon (11) to impact. The explosion of the weapon (11) produces a hot spot that is tracked by the imaging system (31). The hot spot is tracked until a preselected depression angle is reached. The glider (20) banks until the hot spot is at a predetermined angle relative to the centerline thereof. This results in a spiral glide path around the hot spot so that the target area is viewed from all aspects. The spiral path also results in a monotonically decreasing range to the hot spot. The glider may employ a GPS receiver, and the target location in GPS coordinates may be entered into the guidance and control system (40). The glider (20) may be programmed to fly along a specific path or geometric surface in GPS coordinates toward the target. Using a fixed filed of view imaging system (31), a large amount of background is seen from long range and better linear resolution is obtained at short range until the glider (20) descends to the ground. Bomb damage assessment may be performed at the command center within minutes of weapon impact.

Abstract: A cartridge of wound-up photographic film has an elongate housing within which the film is received, the housing having an outlet through which the film leader projects.  In order to insert the cartridge of film into a cylindrical container it is necessary to wrap the film leader around the housing of the cartridge.  A method of inserting the cartridge into the container involves conveying the cartridge into the open end of the container whilst simultaneously rotating the cartridge about its longitudinal axis so that the film leader is brought into engagement with the rim of the open end of the container whilst it is rotating.  This causes the film leader automatically to be wrapped around the housing of the cartridge to permit the ready insertion of the cartridge and the film leader into the container.  An apparatus for automatically performing the function of inserting the cartridge into the container using this method is also described.

Title: Non flickering fluorescent lamp
Inventor: BARSKI WOJCIECH GRZEGORZ
IPC: H05B41/16
Filed: 1996-07-15
Abstract: In a fluorescent lamp, it is known to have a fluorescent tube connected in series with an induction coil (choke), plus ignition device. This circuit is connected to a source of alternating voltage. The fluorescent tube produces light, which flickers with twice the frequency of power lines.  For 60 Hz supply voltage this gives 120 Hz flicker (full ON and full OFF).  Flickering is straining for the human eyes and for rotary/oscillatory movements produces stroboscopic effects, which may be deceiving and dangerous. In this invention, the fluorescent tube gets DC (direct current) constant voltage from work capacitor via induction coil. Work capacitor gets voltage from rectifier. The rectifier gets AC (alternative current) alternative voltage from power lines via capacior in series. That capacitor in series limits the power drawn by the fluorescent tube. The lamp produces steady light.
